With the conventional CT scan, only lymphadenomegalies can be clearly displayed, while lymphatic structures as a whole are not detectable. Therefore, it is routinely employed only for oncological staging. However, if associated with lymphografy, according to Kinmonth method, e.g. with injection of radio-opaque liposoluble contrast medium in the lymph circulation, also lymphatic-lymph node structures can be clearly displayed. In this way, spiral CT scan advantages are combined with those – namely resolution and accuracy – offered by this more specific imaging technique.
